An App is to be launched at the European Dynamic Positioning (DP) Virtual Conference next Wednesday, 24 March (09:00 - 13:00)

The event is a collaboration of the Nautical Institute (NI) and the International Marine Contractors Association (IMCA). 

(As Afloat reported the Irish operated Mainport Geo with a (DP2 system) entered Cork Dockyard in January and following coverage of conversion into a survey and marine scientific vessel, the ship had just departed the graving dry-dock to berth at a nearby quay).

Next week's talk (details below) by Andy Goldsmith of the IMCA is in co-operation with the (NI), a non-governmental organisation with consultative status at the International Maritime Organization (IMO)

The NI and the IMCA have also joined forces to transform the continuing professional development (CPD) of dynamic positioning operators (DPOs) by issuing a dedicated app which will be launched during the talk. 

It’s intended for DPOs who perform a safety-critical role on board offshore DP vessels and need to maintain their technical knowledge. The new app will enable DPOs to expand their professional awareness and understanding of industry guidance, safety bulletins, DP exercises and training drills ‑ all of which will contribute to safety and operational efficiency offshore.

CPD is acknowledged to be an effective way of combatting skills-fade. Allen Leatt, IMCA’s CEO said: "Our DP event reporting scheme reveals that human factors often influence undesirable DP station-keeping events. We are optimistic that CPD will bring a helpful improvement in the safety and risk management of DP operations in our industry."

The CPD modules will be released at six-monthly intervals – and the first module will be available online as soon as the app is officially launched at midday on Wednesday. You can signup for an account via The Nautical Institute’s Alexis Platform in preparation for the module to be released.

The app is designed for use on mobile devices. NI CEO Captain John Lloyd explains: "Using specialist mobile device learning management software, the app is available across a wide range of operating systems. Importantly, it provides offline capability, ensuring the content remains available without internet connection – an important factor for seagoing personnel."

The NI and IMCA are confident that the new app will benefit individual DPOs, by providing a convenient way to keep knowledge and skills current, and the DP industry, by enhancing safety offshore.

#PORTS & SHIPPING – One of the world's largest and most advanced ultra deepwater installation and cable laying construction vessels, the AMC Connector arrived into Dublin Bay this morning, having picked-up a pilot offshore of the Baily Lighthouse, writes Jehan Ashmore.

The Norwegian flagged 19,000 tonnes vessel which was only launched last year is capable of operating in waters beyond 3,000m. She is fitted with Dynamic Positioning (DP3) technology, which allows the vessel to maintain a precise and constant position using satellite technology while operating in harsh weather conditions.

AMC Connector is able to install power cables and umbilicals using its two heave-compensated offshore cranes and a VLS system with pay-load capacity of 9,000 tonnes. There are two carousel turntables for the cables, one capable of handling 6,000mt above deck and the second of 3,000mt capacity is sited below deck. There are two remotely operated vehicles (ROV) and a single centred moonpool in addition to two sliding to the port side.

The 156m ship has accommodation for up to 140 personnel plus a hospital. In front of the bridge and directly above the bow is a heli-deck which is designed for Sikorsky S-92 type helicopters. This is the same type of helicopter that was recently introduced as the new SAR helicopter for the Irish Coast Guard (ICG).

The red-hulled vessel is part of a modern fleet operated by the EMAS AMC, which is an Olso based offshore contractor offering subsea construction, installation, maintenance, repair and decommissioning services. They specialise in complex projects in any environment throughout the world.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

  • Main Propulsion Motor 2000 kw
  • Bow Thruster 780 kw
  • Tunnel thruster 400 kw

Other

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
