Offshore Structure Design
Jacket Design
With extensive experience in offshore structural engineering, we provide expert jacket design services for a wide range of water depths, from 20 to 300 meters. Our comprehensive capabilities encompass in-place (static, seismic, fatigue and so on) and pre-service (loadout, transportation, launch and so on) analysis, along with specialized assessments for appurtanences, such as pile sleeve, flooding & grouting system, and other critical load cases. This integrated approach ensures structural integrity and long-term performance in the most challenging marine environments.
Pipeline Design
We offer full-spectrum engineering services for the design of subsea pipeline and riser systems. Our expertise encompasses detailed pipeline design, and riser system analysis for various applications. Our capabilities include hydraulic and thermal analysis, on-bottom stability assessment, free-span analysis, and fatigue life evaluation. We provide tailored solutions in material selection, wall thickness selection, and installation methodology to ensure the safety, integrity, and cost-effectiveness of pipelines in diverse subsea environments, from shallow waters to deep-sea developments.
Installation Design
Pipeline Installation
We provide full-scale pipeline S-lay installation engineering, and shore pull installation methods for subsea pipelines. Our services include installation feasibility studies, lay vessel selection, and dynamic lay analysis to assess pipeline stresses and fatigue during deployment. We optimize the lay vessel draft, stinger angle， roller support height and lay tension to select appropriate operation status, obtaining the operational environmental condition by static, dynamic and fatigue analysis, which can be used to conduct the installation work.
Jacket Installation Design
Our team specializes in the engineering and execution of jacket installation, covering launch, lifting, pile driving design. We conduct detailed analyses for on-bottom stability, upending analysis, and pile drivability to ensure structural integrity during installation. Our services include load-out and transportation engineering, as well as fatigue and impact assessments for complex offshore environments. We leverage state-of-the-art numerical modeling to optimize installation sequences, ensuring cost-effective and safe deployment of jacket platforms.
Topside Installation Design
We provide comprehensive engineering services for the installation of offshore topsides, ensuring safe and efficient deployment for fixed platforms. Our expertise includes floatover, load-out, transportation, lifting, and mating analysis, utilizing advanced simulation tools to assess dynamic behavior during installation. We offer tailored solutions for heavy-lift operations, considering environmental conditions, vessel selection, and structural integrity. Our capabilities encompass ballasting studies, seafastening design, and motion response analysis to optimize installation methodologies for both shallow-water and deepwater developments.
subsea structure installation
We provide professional engineering services for the installation of subsea structures, including riser, spool, manifolds, jumpers, mudmats, and other subsea equipment. Our technical expertise covers installation methodology design, lifting analysis, ROV-assisted positioning, and precision docking to ensure safe and efficient deployment in complex subsea environments.
Utilizing advanced numerical modeling and dynamic analysis, we assess structural loads during lowering, touchdown, and adjustment, optimizing installation procedures to account for environmental forces such as currents and waves. Our services also include vessel selection, rigging design, and post-installation stability verification to ensure long-term operational integrity.
Heavy Marine Transportation
We deliver specialized float-on/float-off and transportation engineering services for offshore and marine operations, ensuring the safe and efficient movement of oversized and high-value cargo. Our expertise includes float-on/float-off design, seafastening design, motion response analysis, and vessel suitability assessments. We utilize advanced numerical simulations to evaluate dynamic loads during transport, ensuring structural integrity under harsh marine conditions. Our tailored solutions cover float-on/float-off, barge stability, and strength assessment for critical components.
Offshore Platform Decommission/Reverse Engineering
We offer end-to-end decommissioning solutions for aging offshore platforms, including engineering, planning, and execution of safe and environmentally compliant removal operations. Our expertise covers structural integrity assessments, cutting methodologies and heavy-lift removal strategies. We provide risk-based approaches for disposal, recycling, and site remediation, ensuring regulatory compliance while minimizing environmental impact. Our capabilities include rigging and lifting analysis, vessel selection, and offshore execution planning for both partial and complete platform removal.
