Kinh nghiệm chọn hướng giàn - WHP orientation study

Thưa ACE,
Trong giai đoạn conceptual, việc lựa chọn hướng giàn rất quan trọng, nó ảnh hưởng tới điều kiện làm việc, sức chịu tải trọng môi trường của kết cấu và chiều dài cọc tính toán.
Có một số căn cứ goi là philosophy để đặt vị trí của boatlanding, helideck, flare/vent boom, Wellbay, crane...
Rất mong các bác có kinh nghiệm chia sẻ giúp. cái gọi là philosophy thực chất là như thế nào.
Xin cảm ơn.

 

Gửi bác một số thông tin thế này:
The geographic orientation of a platform refers to its position referenced to true North. Platform orientation and configuration is dependent on the following:
· Proximity to existing or future facilities
· Existing and future pipelines
· Predominant winds (influencing operational factors and platform ventilation)
· Prevailing ocean currents and extreme wave direction (also impacts on the substructure design option)
· Support boat movements and mooring location
· Helicopter approach directions
· Flare boom location and orientation.
===================
Topside structure base on Equipment Layout shall be developed to show the followings:
The Helideck is to be located on the East side of platform which is the safest area with respect to the drilling facilities, processing area, flare boom, and exhausts taking prevailing winds into account.
Risers are located on the West side of platform to minimizing pipelines length tie-in and acceptable relative to drop object risk.
Supply boat access and boat landing area shall be provided at the South side of the platform, which is opposite to prevailing wind and current.
Flare boom is located on the West side of platform which is safe relative to prevailing wind
Jack up rig approach is from the North side of platform as layout equipment proposes.
