Abstract

Ship construction generally consists of two main parts: the hull and the superstructure or deck house. Several factors must be considered in the construction of a ship. Planning the characteristics of the ship's hull, we are also planning the strength and structure of the ship itself. Midship construction is a construction that must have serious attention in calculating the ship structure. In this section, many forces are acting so that there is a relatively large risk of structural failure. One of the world's classification institutions is BKI, which provides rules for selecting structural profiles. Based on these rules, the load on ship sides is 71,284 KN/m2. Load on the ship bottom is 76,795 KN/m2, Deck Load on Deck Superstructures is 32,581 KN/m2, Load on Cargo Deck is 57,330 KN/m2, Load on Inner Bottom is 68,212 KN/m2, Load on Accommodation Decks is 3,981 KN/ m2.

Abstract

The offshore oil and gas sector faces significant challenges in reducing its carbon footprint while meeting global energy demand. Offshore structures consume up to 500 MW of energy per day. Despite the potential for 30-40% energy savings with efficiency technologies, only 25% of global platforms implement integrated energy management systems. This study aims to optimize energy efficiency in offshore structures to support SDG 7 - Affordable and Clean Energy. The study uses a multi-method approach, analyzing data from 10 offshore platforms, conducting energy modeling, and cost-benefit analysis. The results show variability in daily energy consumption (423.7 ± 32.5 MW) with key factors such as hydrocarbon production and environmental conditions. Energy efficiency technologies such as hybrid power generation systems and Integrated Energy Management Systems (SMET) show significant potential for savings. The optimization model shows a total potential energy savings of 37.2 ± 2.1%. Economic analysis using Monte Carlo simulations confirms the feasibility of investment with positive NPV for all evaluated technologies. SMET has the most favorable risk-return profile with a mean NPV of 5.8 ± 0.7 million USD. These findings provide important insights for operators and policymakers, emphasizing the importance of a holistic approach to energy management in offshore structures. Implementation of the proposed energy efficiency strategies can contribute significantly to climate change mitigation and the achievement of SDG 7.

Abstract

This study aims to address moral hazard risks in FPSO-tanker oil transfer operations by introducing a semi-quantitative model rooted in stakeholder engagement theory. The model, named SEMHAM (Stakeholder Engagement-based Moral Hazard Analysis Model), incorporates four engagement indicators to calculate the total involvement percentage (PTI): Occurrence Frequency Value (OFV), Responsibility Weight Value (RWV), Critical Role Value (CRV), and Process Impact Value (PIV) to calculate the Total Involvement Percentage (PTI). This metric quantifies the behavioral influence of each stakeholder in the offloading process. Using operational data from 17 offshore zones based on Pertamina's 2023 report, eight primary stakeholder roles were evaluated using a weighted activity matrix. The findings indicate that FPSO Crew and Ship Crew possess the highest PTI scores, signifying greater control and potential risk, whereas administrative actors such as agents and port authorities were identified as lower-risk participants. The SEMHAM model facilitates risk classification and recommends appropriate digital oversight, including IoT-based monitoring, smart contracts, and role-based dashboards. This approach enables the integration of behavioral risk metrics into digital governance systems, thus supporting real-time operational monitoring. The model also demonstrates potential scalability to more complex offshore energy domains, such as LNG terminals and deepwater operations, enabling broader stakeholder governance beyond the current FPSO-tanker context.
