The existing King Post for New 60’ Burner Boom was found to be inadequate due to excessive corrosion and insufficient strength.  So, for installation of Boom on vessel, New Kingpost is designed (for Stbd and Port). Burner Boom & King Post is analyzed for new Environmental condition. Deck structure is analyzed for Loads imposed by Burner Boom & King Post.

The Kingpost is designed as Truss structure with a Platform at the top of Structure and an access ladder. The platform is provided for access to rigging accessories and for locking & unlocking Burner Boom. King Post footings are decided considering present deck obstruction. Truss type structure is selected considering crowded deck area. King post in inserted into transverse web frames due to high support reactions.

It involves the design of stacking arrangement of Boom on King post during Transit condition and design of wind stays to support the boom horizontally against wind. Appropriate locking arrangement is provided to stack the boom on King post. Locking arrangement is spring operated & designed such way that it operated automatically with less manual attention. The Stacking of Burner Boom is facilitated by Wire Ropes, Snatch blocks and Air Winch. The Air Winch is placed in the Kingpost itself to save deck area.

The Burner Boom and Kingposts are analyzed for severe Environmental condition of Vertical acceleration of ‘1g’ and lateral acceleration of ‘0.5g’ and wind speed of 97 knots.  Burner Boom structure is modeled in 'SACS' and King Post & deck structure is modeled in 'SESAM'.
