ESNA unveils small SES workboat Sea Puffin

What is thought to be the world’s smallest surface effect ship (SES) workboat is being built in Denmark for operation on wind farms.

The 15.8-metre-long Sea Puffin is being constructed for Wind Partner, which plans to charter the boat to operators.

Developed by Norwegian naval architects Espeland & Skomedal (ESNA), Sea Puffin features a catamaran hull with fabric skirts enclosing the air cushion between the hulls. It is designed to be capable of being launched with a standard 15-tonne single point davit system.

Sea Puffin is powered by a pair of 230kW diesel engines that are coupled to water jets. These will give a speed of 25 knots.

In addition to transferring technicians to wind farm turbines, the SES is also capable of carrying cargo. It will have a range of 150 nautical miles.
