A proven track record in
marine electrical work

Please take a look at some of the specialist
electrical work we have undertaken recently…


Northern Europe’s largest shipping company – DFDS Seaways

The SeaKing Group have recently supported Northern Europe’s largest shipping company – DFDS Seaways. Our team of electrical designers, engineers and project managers have proudly completed works for the DFDS’ ‘D-Class’ ferries – Dover Seaways, Dunkerque Seaways and Delft Seaways, plus one of the newer vessels, Cotes d dunes which joined the fleet in February 2016.

From brief to completion, all works were completed within a tight project schedule. The restrictions of the pandemic created new challenges, however, with no compromise of workmanship, and ensuring all the team worked in a safe environment.

Working in the Dunkirk-based yard works for the D class vessels included installing the AI system and fuel monitoring plus LED conversions. Onboard the Cotes d dunes, we carried out maintenance and upgrades to the ships’ systems. These works included a new UPS system, a ballast water fibre installation and cabling for the Kongsberg system.

UK’s first large ship-to-shore commercial connection installation in Stromness as part of a green power project.

MV Hamnavoe operated by NorthLink Ferries’ recent works by the SeaKing team. UK’s first large ship-to-shore commercial connection installation in Stromness as part of a green power project.

SeaKing were invited to the project because of our expertise on both marine and land projects; collaborating with Schneider electrics. The partnership was to ensure complete integration with both land and vessel-based systems.

Working with Schneider’s marine technical team, North Link Technical Manager and Technical Superintendent, the SeaKing Group are in the final phases of completing the installation of the MV Hamnavoe shore power installation, including automated control via the Kongsberg PMS (Power Management System).

The need for the installation – initiated out of the Cold ironing standard IEC 80005-3, low voltage shore requirements. A specification required to connect to shore power reducing emissions while the vessel is in port.

The MV Hamnavoe operates in the Orkneys on the route between Scrabster and Stromness, where the weather environment and heavy seas make installation works challenging while maintaining safety.

The project was installed in phases so as not to interfere with the ferry operations.

Ist Phase December 2018 -March 2019

Manufacture of the extension to the switchboard, a new shore power connection Panel both completed with full factory acceptance tests (FAT) 

2nd Phase July 2019

Installation of onboard cable tray, penetrations and cabling. installation of the extension to the main switchboard and cables & containment from the engine control room (ECR) to six deck aft, where a new equipment house had been constructed by the vessel to contain the IP56 rated 415V shore power panel and auxiliary power supplies.

3rd Phase December 2019

Our personnel sailed with the vessel to Stromness during the day and commenced work while the vessel was in port overnight. Setting to work the manual operation aspect of the new ship installation works for preparation of possible use during the forthcoming dry-dock period.

Ft Viv Bridge

RFA Fort Victoria Bridge Refit

Wide-ranging work was carried out to ensure full compatibility with the International Maritime Organisation (IMO) MARPOL regulations. Improvements to the Replenishment at Sea (RAS) equipment will now enable the vessel to replenish the new Queen Elizabeth Aircraft Carriers. Meanwhile, an upgrade to the Bridge section will ensure a modern approach to naval navigation.

SeaKing Group Managing Director Dave Gillam said the firm was initially tasked by Cammell Laird and the MoD to provide a feasibility study which would later form the basis of the Bridge design.

“After carrying out a full inspection of the Bridge area we submitted a series of options to the MoD ranging from minimal work to a complete overhaul of the layout with significant changes to the ship structure,” he said. “The decision was then made to strip the entire interior of the Bridge back to its shell and replace it with a more efficient layout.

“The new design was based around previous installations on RFA vessels which SeaKing had delivered in close partnership with Cammell Laird. It involved the installation of four separate consoles. SeaKing was responsible for the overhaul and reconfiguration of legacy equipment and the installation of new equipment. This included the new RADAR’s, Warship Electronic Charting Display & Information System (WECDIS) and the Navigation Distribution & Conning System (NDACS).”

Alongside other nominated sub-contractors, SeaKing was also tasked with full system integration within the Bridge section. This included the set up and synchronisation of key equipment such as steering gear, signals and controls, wind speed and direction, gyro inputs, ships speed log, pitch and roll, ships AIS, voyage data recordings, main engine and propulsion signals, new NVG compatible navigation lighting and associated controls, and numerous other naval communications systems.

Additional work involved the design, manufacture and installation of a new deck lighting control system. This was achieved with an HMI Touchscreen providing automated control.

On completion of the project SeaKing received commendations from both RFA Superintendents and OEM Directors on the level of diligence, workmanship and effort to complete a specification which was not fully developed at the outset.

The SeaKing Group were engaged by Naval Architects Houlder ltd to survey the 415v switchboard prior to the proposed installation of 5 new 400kw Caterpillar Generators complete with C18 engines. Calculations for fault levels were undertaken, completed and submitted to class.

Then in conjuction with A&P Falmouth shipyard’s project team we removed existing redundant cables and carried out modifications of the switchboard to incorporate new circuit breakers, generator controls and generator repeater panels. The existing generator circuit breakers were upgraded from obsolete Merlin Gerin Selpact range to modern Schneider Masterpact units complete with Micrologic 5.0P controllers. New generator starting batteries, generator control panel, power supplies were installed. Interfacing the new generator control panels into the ships alarm system. Finally we demonstrated generator operations and shutdown alarms to Lloyds.

The SeaKing Group carried out complex cabling work on the vessel for Cammell Laird. The project saw the ferry split in half with a new middle section inserted. This required SeaKing to cut, upgrade and reconnect electrical systems via the new section.

“Key aspects involved mapping the existing electrical system and upgrading infrastructure to drive greater efficiency. All the existing cables were mapped with the addition of new cables for the new control systems. A new propulsion engine and propeller unit was installed together with a new bow thruster fitted to improve operation in high winds. These systems needed to be controlled from both the bridge and the bow. A new auto-pilot system was also fitted. In total, the project involved 60pc new electrical installation work and 40pc refurbishment work to the existing system.”

The SeaKing Group also installed a fire detection panel and removed the radio and navigation systems to allow the vessel interior to be repainted before re-installing them.

MV Chartwell

This project included a complete strip out and rewire of the survey vessel ‘MV Chartwell’ plus the remanufacture and installation of new 220v distribution board and bilge pump controls. The SeaKing Group engineers also installed new fire detection, data and communications systems as well as supplying and fitting two new Stamford generators. We also completed a full bridge instrument refurbishment.


Liverpool Viking

This project was a fault finding mission on a bow thruster generator which had a tripping problem. The SeaKing Group engineers noted that the frequency and voltage curves did not appear correct for the method of starting and it emerged that the voltage was collapsing during the initial load increase. This in turn pointed towards an excitation or AVR problem. Our team of engineers solved this problem by fitting a new AVR.


The Delta ARRC Rig support Craft

The SeaKing Group provided a team of 4 electrical installation personnel, who over a period of six months have installed the entire electrical system on a sequence of eight workboats. The workboats are designed for the support of offshore facilities and personnel.
