در جا های مخازن بتنی و فلزی در فراساحل ساخته می شود حتما باید شمع کوبی یا شمع به صورت در جا استفاده شود اگر به صورت بستر سازی اجرا شود حتما مخازن بعد از چند سال نشست می کند و باعث خسارت می شود.

قرارداد این نوع پروژه به صورت (EPCI) است در پایان به طور مفصل اشاره خواهم کرد.

PlutaoSaturno Venus Marte نام4 محل های از 31 بلوک است که در زیر اقیانوس اطلس جنوبی نفت از آنجا استخراج به عمل می آید. دارای ظرفیت پردازش 157000 بشکه نفت در روز با ظرفیت ذخیره سازی از 6/1 میلیون بشکه نفت است. همچنین قادر به پردازش 245 میلیون فوت مکعب در روز گاز می باشد.

قرارداد های که در کارهای نفتی و پتروشیمی کاربرد زیادی دارد.

قرارداد EPC چیست؟   /What is EPC Contract 

این نوع قراردادها معمولا برای پروژه های عظیم و یا با تکنولوژی بالا منعقد می گردد. در این قراردادها طراحی، مهندسی، تدارکات واجرا همگی به یک مجموعه واگذار می شود.

قرارداد با لحاظ نوع قیمت بر اساس بر آورد کلی با قیمت مقطوع

قرارداد کلید در دست Turn Key چیست؟ /what is turn key contract

قرارداد کلید در دست Turn Key یکی از انواع قراردادهای بر آورد کلی قرارداد کلید در دست است. روش کلید در دست مسئولیت طراحی و اجرا را به طور کامل به پیمانکار واگذار می کند بگونه ای که بعد از تکمیل پروژه، کارفرما فقط با چرخاندن یک کلید و بدون هیچ اقدام دیگری بتواند بهره برداری از پروژه اجرا شده را آغاز نماید.

تلفیق مسئولیت های طراحی با اجرا همچنین امکان کاهش زمان کلی تکمیل پروژه یا به عبارتی اجرای سریع Track Construction Fast را فراهم می کند. در این حالت کارفرما یا مشاورین او فقط در فرآیند مناقصه و نظارت عالیه بر کار پیمانکار دخالت خواهند داشت. کلید در دست نهایت سپردن مسئولیت طراحی و اجرا به یمانکار  را بیان می کند. بنابر این در مشکلات احتمالی نیازی نیست که مشخص شود آیا این مشکل به دلیل ضعف بوده یا از اجرای نادرست ناشی شده است و به عنوان یک قانون کلی، هر عیب و نقصی که در محدوده تعریف شده کار رخ دهد پیمانکار مسئول آن خواهد بود.

Description

Located on Block 31 in the ultra-deepwaters of Angola, the PSVM project is a hub field development that will produce from the Plutao, Saturno, Venus and Marte oil fields. Comprising the northeast sector of the license about 249 miles (400 kilometers) from Luanda and in waters measuring 6,562 feet (2,000 meters), PSVM is the first of four planned development projects on Block 31.With waters ranging from 4,921 to 8,202 feet (1,500 to 2,500 meters) deep, Block 31 spans 1.3 million acres (5,349 square kilometers). Acquired in 1999, BP serves as operator of Block 31 with a 26.7% interest. Project partners include ExxonMobil with 25%, Sonangol with 20%, Statoil with 13.33%, Marathon with 10% and TEPA with 5%. Sonangol also serves as concessionaire of the block

Block 31 Discoveries

Plutao, Saturno, Marte and Venus

The first discovery on Block 31, Plutao was drilled in September 2002 by the Leiv Eiriksson semisub in 6,627 feet (2,020 meters) of water. Reaching a total depth of 13,357 feet (4,100 meters), the discovery well tested at a daily rate of 5,357 bopd.The second discovery made on the block in July 2003, is the Saturno oil field. which was drilled by the Leiv Eiriksson in 5,919 feet (1,804 meters) of water. Located 9 miles (14 kilometers) northeast of the Plutao well, Saturno-1 was drilled to a total depth of 15,443 feet (4,707 meters) and tested at a rate of 5,000 bopd

In November 2003, Marte was the third discovery made on Block 31, approximately 12 miles (20 kilometers) from the previous wells. Drilled to a total depth of 13,757 feet (4,193 meters) in 6,562 feet (2,000 meters) of water, Marte-1 flowed at a rate of 5,200 bopd in tests.Drilled in June 2004 in waters measuring 6,562 feet (2,000 meters), Venus was the fourth discovery made on Block 31. Located 7 miles (11 kilometers) from Saturno, Venus encountered three oil-bearing reservoirs

PSVM Field Development

In an effort to develop the entire block efficiently, the project development has been standardized, including the design, fabrication and commissioning. Authorized by Sonangol in July 2008, the field development plan for PSVM encompasses 48 subsea wells (including production and water- and gas-injection wells) connected to 15 manifolds, and 106 miles (170 kilometers) of flowlines and 59 miles (95 kilometers) of control umbilicals linking the production to a converted FPSO.

Halliburton was chosen to provide well completions services for PSVM, including upper and lower completions equipment, downhole flow control, and drilling and completions fluids.

Future Development

Comprising four of the 16 discoveries on the highly proficient block, PSVM is the first of four planned development projects for the license. With plans for more than 150 production wells over the license, Block 31 is being developed in phases. Project partners have standardized the Block 31 development concept in an effort to bring all of the fields into production more quickly. In effect, the other three development plans should closely mirror that of PSVM (aka a subsea development linked to an FPSO), and multiple contractors on the PSVM project have been tapped for the next three projects. For example, Subsea 7 signed a contract for call-off services on all four of the developments, as well as Heerema and Halliburton.

Currently in the planning stage, the next project will incorporate the fields in the southeast area of Block 31, which include Palas, Ceres, Juno, Astraea and Hebe. Another group of fields are clustered in the northwest section of the block. These fields include Urano, Titania, Terra, Portia, Miranda and Cordelia. The 16th discovery, Dione is located in the southern section of Block 31

PSVM FPSO

Under Construction - Jul 31, 2008 to Dec 2012

Currently being converted from a tanker, the double-hulled PSVM FPSO will have a storage capacity of 1.6 MMbo and a processing capacity of 157,000 bopd. The production facilities aboard the vessel include oil separators, gas injection/gas lift equipment and water injection equipment. Being built to operate for 20 years without the need to dry-dock, the vessel will house a SOFEC external turret mooring system for mooring in waters 2,000 meters deep. First oil is expected in 2011
