Conversion 2D seismic survey vessel 'HARRIER EXPLORER'

At the end of 2006, Niestern Sander received an inquiry from Seabird Exploration in Dubai for the conversion of a supply vessel to a seismic survey vessel. A delegation from Niestern Sander paid a visit to the ship to orientate itself on this request. Apparently the visit made a good impression: a few weeks later the owner visited the shipyard in Delfzijl. The contacts resulted in a contract.

Additional accommodation

The Harrier Explorer sailing under Panamanian flag arrived in Delfzijl in December 2006, where a rigorous metamorphosis awaited her. The existing accommodation was widened on both sides of the bridge to the entire width of the ship. This created spaces for technology, fitness, recreation and conferences. Behind the existing structure, a new accommodation block was installed with 14 cabins and a research area.


A hangar of 40x20x10 meters was installed on the afterdeck. Here winches and hydraulic equipment were placed to tow and take on board seismic equipment. For that purpose, the stern was converted into slipway.

Inside the vessel

Invisible to the outside world was the extensive work that took place inside the vessel. Various specialisms were outsourced, such as the removal of asbestos, the E-work, the laying of pipes, the carpentry and the hydraulics. The existing accommodation was completely stripped, as was the command bridge. Here all equipment was replaced and expanded. Furthermore, a new galley was set up to serve 60 people.

The work, in which the carpentry department also participated, was completed in September 2007. A total of 325 tons of steel was processed; one of Niestern Sander's largest conversion projects.
