Shell Leman Bravo (North Sea)

Shell Leman Bravo - QuikDeck Suspended Access

Large-scale deconstruction work


Barge Campaign Shell Leman Bravo (BD/BP platform)


The conversion of the BD/BP platform fits in a series of decommissioning projects in which we are involved. What made the implementation of this project different was the large-scale use of the modular work platform QuikDeck®. 


This innovative system created no less than 3,000 m2 of work surface on the bottom of the platform. In addition, approximately 18,300 m3 of TubeLock scaffolding was constructed and everything was covered with 2,380 m2 of Deltaplane tarpaulin.

Flat and open work floor

An average of 20 scaffold builders, some of whom specialized in rope access, worked in shifts every day. These employees were also deployed at the start of construction of the QuikDeck® platform.

All remaining scaffolding material from the previous access subcontractor had to be dismantled and removed by us (100 tonnes in total). The QuikDeck® platform enabled this dismantling to be carried out efficiently and safely. QuikDeck® creates a stable, flat and open space, allowing teams to work quickly and safely. The platform can be assembled 'in the air' and also has a large load-bearing capacity.

Large painting jobs

Redundant installations and facilities, such as a helideck, vent stack, cranes and platforms were also removed.

The decommissioning activities resulted in the removal of 380 tonnes of old steel. The remaining structures and installations of the platform were then provided with a new coating system. A total of 29,000 m2 of painting was carried out by an average of 25 employees every day. The legs and jacket of the Leman Bravo platform were blasted and coated by rope access specialists.

Strong logistic capabilities

All the materials required for this project were transported from Beverwijk in 20FT containers, with a maximum load of six tonnes, to the Brand warehouse location in Great Yarmouth. From there, the containers were transported by boat to the platform. During the first three months, six to eight containers were delivered weekly via this route.

The removal of materials began two months before the end of the project. Sometimes as many as ten full containers returned, via Great Yarmouth, to the offshore warehouse in Beverwijk.

The renovated Leman Bravo platform, which was also fitted with solar panels, is controlled from the main platform. The gas that comes in through the wells is collected in a manifold and transported to the main platform Leman Alpha. Further maintenance on the Leman Bravo will be minimal in the coming years. The platform will then only be accessible by water via the Walk-to Work maintenance vessels Kronenborg and Kasteelborg.


Leman Field

The Leman Field is located in the southern part of the English continental shelf. The Leman gas field was discovered in December 1965 and consists of three large complexes, Leman A, B and C and four additional platforms, Leman D and E in the south and Leman F and G in the north.

The life of the field is expected to last until 2032. The Shell-operated Leman B complex consists of two pairs of bridge-connected platforms, Leman BT / BH and Leman BD / BP.
