A position of power

Kongsberg Maritime’s Dynamic Positioning system makes anchor handling easier and more efficient for both crew and vessels.

Normand Drott, the 15-year-old flagship of Norway’s Solstad Offshore’s anchor handling fleet, relies on Kongsberg Maritime’s Dynamic Positioning (DP) system to stay competitive as demand for anchor handling tug supply (AHTS) vessels heats up offshore.

The 95-metre anchor handling vessel is a byword for reliability in offshore operations as at the heart of the vessel is the K-Pos DP control system, a crucial component in stability and fuel efficiency, even in heavy seas.  Launched in 2010, Normand Drott has a bollard pull of 339 tonnes and a 760-sq. metre deck. It is the flagship of Solstad’s fleet of 10 AHTS vessels.

Its captain, Jens Goderstad, is proud of his vessel’s versatility. He says: “We mainly do anchor handling and project work related to offshore operations like moving rigs, anchoring them up, mooring up big offshore assets that are going to be used for production of oil and gas.” However, Jens also points to operations beyond offshore oil and gas, with past projects including floating wind farm installations (Hywind, 2017) and even anchoring cruise vessels.

Normand Drott shows no signs of slowing down and the key to its longevity is its K-Pos system. Reliability in station-keeping and stability during operations are vital, says Captain Jens, especially when the crew are working with heavy equipment or connected to subsea assets.

A robust and safe system

Captain Jens says that the DP system on Normand Drott keeps the vessel very stable during sensitive work such as cable and hose handling or ROV launch and recovery, even in tough seas. He says weather limits on his vessel’s DP system are usually higher than for the operations they conduct. “In many cases, the operation stops before the DP stops,” he says. 

The K-Pos DP is also easy to operate, a big plus for the crew. “It is among the easiest systems to use,” says Jens. “It’s easy to understand the different functions, the modes and how to operate it. It is also robust and it doesn’t change too much. We don’t need new things all the time.”

A DP system gives a stable platform to work from. We will have full control of the vessel and its movements, and we’ll be able to keep the vessel in position, which usually can be quite critical. 

The DP system has so many redundancies that I feel safe when I’m using it… I don’t feel I [will] lose control of the vessel. When I tell the DP what to do, I know it will do it.

Cutting fuel, saving the sea

One of Solstad Offshore’s long-term goals is cutting emissions. In 2009, the company began a campaign to find ways to cut fuel use and emissions. Kongsberg Maritime became a partner in this plan when it signeda decarbonisation agreement with the company in 2023.

Kongsberg Maritime’s DP system features a special mode, allowing Normand Drott to stay on station in DP while reducing fuel consumption by up to 20 per cent.

The DP helps us to reduce the loads on the engines and then the amount of fuel we are using, we can see that we save some fuel every time. So, we save the environment and save running hours on the equipment on board.

Challenges and changes are inevitable, and Kongsberg Maritime helps customers address issues as they arise, according to Captain Jens. That help is vital to Solstad Offshore, as all its vessels have Kongsberg Maritime equipment onboard. Normand Drott has Kongsberg Maritime winch systems, cranes, steering systems and thrusters, all working together to achieve maximum efficiency.

This integration ensures compatibility and efficiency across various systems. The TowCon operating system, for instance, manages all the winches. Bjørnar describes it as “the brain of the whole winch package”. 

Yet, a system is only as good as the network supporting it. Solas stresses how Kongsberg Maritime keeps his vessel running at maximum capacity. “Kongsberg Maritime has a good service package. They visit the vessel regularly, updating all the software. We know we have the latest technology.”

Captain Jens says it is not always easy to adapt to new technology: “As we see from the contact we have had with Kongsberg Maritime, they are good at reaching out to us and helping us with our challenges, and to try to solve them together, so that we can create the result that our customers want.”

The offshore industry may be facing new challenges in efficiency, but it is collaboration between innovative companies such as Solstad and technology leaders like Kongsberg Maritime that is shaping the future of offshore operations.
