Editor's Notes
- Established in August 2011 between ICD AS and Marine Aluminium AS as ”a technology and marketing collaboration that will contribute to increased efficiency and safety for offshore vessels and marine installations.”
- You have heard about ICD today, the developer of very advanced control systems. Marine Alu is a well-reputed constructor of helidecks and large, passive gangways. They have built offshore equipment for over 40 years, with 60 gangways and 600 helidecks as their main products.
- UPTIME uses the products and technology from these two companies to create their good, mainly the motion compensated helideck and gangways. I will introduce you to the problem that the gangways shall solve first:
- The main objective for this vessel is to transport the crew to and from the installation in a safe and timely manner. I assume that most of you agree that this does not seem very safe, do you? As you can see on the right, people are getting ready to swing over with ropes. Please note that this is in fairly good weather, with small swells. During worse conditions, this cannot be done. The access platform will be a dangerous place and the movement of the vessel will be excessive. The only option then is by crane and basket, as demonstrated here: (CLICK)
- This is seen from the deck of the installation. The crane operator sees more or less the same. How easy is it to hit the deck, and how can you judge the up and down motion? Is this safe? We only see three people, but it is common to load the basket with up to 10 people. This is also during good conditions, imagine doing this in gusty winds or heavier seas! Fortunately this ends good…
- Accumulators on the side and one of the two pump motors on the outside. The radiator on top is for air cooling, so the system can be used in +40 to -20 C conditions.
- This shows the telescopic pedestal on Island Crown in the upper and lower position.
- Main advantages: enclosed walls, good railing, 1,2m width
- Enclosed roof, emergency battery lights, siren and alarm light. Can also be fitted with night vision light, if the gangway is in the line of sight of the bridge.
- Typical long term layup with the landing cone and lashings on the side. The lashings are necessary, as the gangway can be moved off the platform in heavy winds when the system is in passive mode. If the reach is extended or contracted, the system will lift an the lashings will come off automatically.
- Modern user interface with touch screen. The green sectors are OK, yellow are alarm sectors and orange and red is exceeded limits. The system will auto-lift when in the red zones.
- This is a bumper landing on the HyWind wind turbine from Island Crown
- The second delivery is for MAC offshore and Shell Brunei. This will be ready by the end of the year.
- We do wave analysis of the RAOs to analyze if the gangway reach and response is adequate for the vessel in question. This is done in cooperation with the vessel owner and hull designer. We get weather data from the area the vessel is supposed to operate, so we can ensure that typical conditions are being considered.
- The first delivery in 2013 is for Island Crown. Welcome on board this vessel during Nor-Shipping in Oslo in June.
- The second delivery is for MAC offshore and Shell Brunei. This will be ready by the end of the year.

- The SIEM vessel will be ready in 2014 and is the first pure windfarm maintenance vessel built. This brings us over to the other units we produce, which are typically for near-shore access to windfarms or oil installations.

- Fast-paced video of use at Trianel Borkum West 2 This brings us over to the other units we produce, which are typically for near-shore access to windfarms or oil installations.
- This includes faster crew vessels with a cruising time of a max of 1-2 hours. The vessels get bigger and bigger, and exceed 200 tons. Typically, these vessels have been allowed to push on in order to stick to the access ladder. This is not practical in heavy seas and with larger vessels with high buoyancy and weight. We have made the access gangway as a shock absorber, which lets the vessel float freely while the crew walks across.

- The gangway has a grip on the end, which will grip the access ladder on a wind turbine or oil installation. The system is lightweight, inexpensive and very safe to use.
