OTEC 模块可减少深水回接电力供应的资本支出和排放

2024 年 11 月 14 日
新系统利用海洋热能转换(OTEC)技术为远程海上平台和油井提供动力,旨在为传统的长海底回接提供替代方案。

Global OTEC在里约热内卢举行的第一届巴西地热能利用与储存研讨会上推出了用于海上能源勘探和生产的 OTEC 动力模块。

该系统利用海洋热能转换 (OTEC) 技术为远程海上平台和油井提供动力,旨在为传统的长海底回接提供替代方案。

该电源模块旨在提供清洁的基载电力和流量保证服务,无需电缆和液压系统,后者通常会将覆盖范围限制在 35 公里以内。

据Global OTEC称,该动力模块可将深水长海底回接资本支出削减20-30%,同时还能提高运营效率并减少二氧化碳甲烷排放。

OTEC 平台立管开发的全球合作伙伴2H集团董事总经理 Yann Helle 表示:“这项技术为海上油田开发开辟了新的可能性,特别是在传统能源供应成本高昂或物流困难的地方。”

该模块采用有机朗肯循环,利用温暖的表层海水和寒冷的深层海水,利用海洋的自然温度梯度。据说这使该系统能够在全年任何时候持续产生清洁电力。 

每个电源模块可提供高达 500 kW 的安装容量,并且各自配备安全和控制系统以支持本地和远程操作。

Global OTEC 首席工程师 Sam Johnston 补充道:“我们的团队开发了 OTEC 动力模块作为无人解决方案,与现有的海上系统集成,确保稳定性和效率。”

最近,该公司在休斯顿建立了新基地。

Global OTEC 创始人兼首席执行官 Dan Grech 补充道:“我们的技术为海上石油和天然气作业增加了价值和效率,提供了可扩展、经济高效的能源解决方案,从而提高了油田经济效益。这一途径对于解锁更大规模的 OTEC 项目至关重要,这些项目将能够取代 FPSO 上的燃气和柴油涡轮机。”

OTEC module could cut capex, emissions of power supply for deepwater tiebacks

Nov. 14, 2024
A new system uses the Ocean Thermal Energy Conversion (OTEC) technology to power remote offshore platforms and wells, and it is designed to provide an alternative to traditional long subsea tiebacks.

Global OTEC has unveiled its OTEC Power Module for offshore energy exploration and production at the 1st Brazilian Workshop on Geothermal Energy Utilization and Storage in Rio de Janeiro.

The system uses the Ocean Thermal Energy Conversion (OTEC) technology to power remote offshore platforms and wells, and it is designed to provide an alternative to traditional long subsea tiebacks.

The power module is engineered to deliver clean baseload electricity and flow assurance services without the need for cables and hydraulics, which typically restrict reach to 35 km.

According to Global OTEC, the power module could cut deepwater long subsea tieback capex by 20-30%, while also bringing improvements in operational efficiency and reduced CO2 and methane emissions.

“This technology opens up new possibilities for offshore field development, especially in locations where conventional energy supply is costly or logistically challenging,” said Yann Helle, group managing director at 2H, global partner in the OTEC platform's riser development.

The module employs an Organic Rankine Cycle to harness the ocean's natural temperature gradient by drawing on warm surface seawater and cold deep water. This is said to enable the system to generate continuous, clean electricity at all times throughout the year. 

Each power module can provide up to 500 kW of installed capacity, and they are each equipped with safety and control systems to support local and remote operation.

“Our team has developed the OTEC Power Module as an uncrewed solution to integrate with existing offshore systems, ensuring stability and efficiency,” added Sam Johnston, lead engineer at Global OTEC.

Recently, the company established a new base in Houston.

“Our technology adds value and efficiency to offshore oil and gas operations, providing a scalable, cost-effective energy solution that enhances field economics,” added Dan Grech, founder and CEO of Global OTEC. “This pathway is essential for unlocking larger scale OTEC projects that will be capable of replacing gas and diesel turbines upon FPSOs."
