更好地计算海洋中波浪活动的需求从未如此迫切。

海上工业继续将作业转移到更深的水域和更恶劣的环境中。操作边界被拓展,工作窗口被减少。更具挑战性且不断变化的海上波浪和天气条件仍然是海洋环境中步行上班或定期检查、维护和修理等操作的固有风险。

对于一个需求积极且预计未来几年将进一步增长的行业来说,对运营效率的需求以及在更危险的海洋区域的近海人员安全的需求将面临越来越大的压力。

监测海上条件

对于在海洋环境中运营的公司来说,它证实了继续寻找更好地监测和共享海况数据的方法的重要性。这将确保操作能够尽可能安全有效地完成。

数字化的力量正在推动公司的工作方式和实现目标。数字化转型有助于扩大数据源并增加行业的知识和专业知识,突破界限并将创新提升到新的水平。

使用先进的数字工具(例如干式物联网 (IoT) 和云传感器)进行海洋数据收集和评估,以收集有关海况或天气状况的实时信息,不仅可以提高安全水平,还可以显着降低成本节省。

Miros Group 的 RangeFinder 是一款高频垂直微波雷达,可提供海平面、潮汐、非定向波监测和气隙测量。它可用作基于物联网的传感器。因此,它是真正的即插即用,只需要电源和互联网连接即可安全地访问有关海洋状态的即时、实时数据。该技术为气象浮标提供了可靠且强大的 21 世纪替代品,气象浮标一直是海况监测业务的支柱。

有了如此高精度的干波传感器,我们比以往任何时候都更有能力对海况进行可靠、准确的评估,与负责就业务活动时间做出关键决策的人员实时共享信息,并最大限度地减少“等待天气” ,”这通常提前几年安排到项目计划中。

显然,这不是一朝一夕的过程。数十年来,为了满足全球海洋离岸市场对更精确、更可靠的海洋洞察的需求,海况监测的改进和发展一直在不断进步和发展,并且该行业不断突破可实现的界限。

船舶操作通常基于主观观察,这很容易受到挑战。了解波浪的运动和活动以及操作员进行天气敏感操作的能力通常依赖于天气预报和海况条件的视觉感知的结合。

这种决策过程至今仍在使用,也许海员的直觉永远会发挥作用,但对更新、更复杂、更可靠和准确的海上天气预报方法的需求仍在快速增长。

持续提高效率和变革的动力来自被迫降低项目总体成本的行业,以及承包商或船舶运营商希望最大限度地减少对环境的影响,同时进一步提高竞争优势,同时提高安全水平。为了能够提供涵盖所有这些需求的全面决策支持,供应商和用户之间必须进行值得信赖的合作。

直接获取实时海况数据 

通过海况即服务模型,可以轻松地同时检索数据并与所有内部和外部项目利益相关者共享数据。这使利益相关者能够全面了解环境状况的发展,无论人员是在岸上还是海上。此外,它还为船舶进出规划提供了宝贵的支持,促进了操作期间的实时决策支持,提供了对历史数据的访问以进行操作后分析,并提高了对数值频谱预测和改进阿尔法因子的信心。

阿尔法因子对于波高和周期是合同履行的关键因素的操作非常重要。Miros 技术获得了 DNV 的认可,可以向客户保证他们接收到的数据是准确的,并且可以通过扩大天气窗口和最大限度地减少等待天气的时间来提高可操作性。此外,允许船舶持续更长时间的运营可以节省成本并提高项目期间的效率。从本质上讲,Miros 的目标是帮助客户最大限度地提高船舶的可操作性。

通过安全云解决方案实时共享的海况数据使海洋部门能够受益于人员移动操作安全性的提高,与商品波浪测量技术相比,显着降低了成本,并提供了高数据可靠性和可用性,从而显着提高了可操作性。

最关键的方面是能够将实时数据与建模或预测数据结合使用,捕获这些数据是为了提高安全性和运营效率。获取海况实时信息直接影响在日常操作(例如设备部署、海底设施、电缆或管道铺设或船员转移)期间开展海上活动或监测海况的决策。

Opinion: The value of understanding waves

March 22, 2023
There is a greater need to reliably monitor and document offshore conditions as the industry continues to move operations into deeper waters and harsher environments.

By Andrew Wallace, Miros Group

The need to better calculate wave activity in our seas and oceans has never been more critical.

The offshore industry continues to move operations into deeper waters and harsher environments. Operational boundaries are pushed, and work windows are reduced. More challenging, as well as changing, wave and weather conditions offshore remain an inherent risk for operations such as walk to work or scheduled inspection, maintenance and repair in the marine environment.

For an industry entering positive demand with further growth expected over the coming years, the need for operational efficiency combined with the safety of personnel offshore in more hazardous marine areas will be under increased pressure.

Monitoring offshore conditions

For companies operating in the maritime environment, it confirms the importance of continuing to identify ways to better monitor and share sea state data. This will ensure operations can be completed as safely and efficiently as possible.

The power of digitalization is driving the way companies work and what can be achieved. Digital transformation is helping to expand data sources and increase the industry’s knowledge and expertise, pushing boundaries and taking innovation to new levels.

The use of advanced digital tools like dry-mounted, Internet of Things (IoT) and cloud-enabled sensors for ocean data collection and evaluation to gather real-time information about sea state or weather conditions is not only improving safety levels but achieving significant cost savings.

Miros Group's RangeFinder is a high-frequency vertical microwave radar providing sea level, tide, non-directional wave monitoring and air gap measurements. It is available as an IoT-based sensor. So, it is truly plug-and-play, only needing power and an internet connection to give secure access to immediate, real-time data about the ocean state. This technology delivers a reliable and robust 21st-century alternative to the weather buoys, which have been the mainstay of the sea state monitoring business.

With such highly precise dry wave sensors, we are better equipped than ever to make a reliable, accurate assessment of the sea state, sharing information in real time with those responsible for making crucial decisions about the timing of operational activity and minimizing "waiting on weather," which is often scheduled into project plans years in advance.

Clearly, this is not an overnight process. Refinements in sea state monitoring have been advancing and developing for decades, in response to demand from the global marine offshore markets for ever more precise and reliable ocean insights, and the industry continues to push the boundaries of what can be achieved.

Vessel operations are often based on subjective observation, which is open to being challenged. Understanding the movement and activity of the waves and operators’ ability to carry out weather-sensitive operations often rely on a combination of weather forecasts and visual perception of sea state conditions.

This decision-making process is still in use today and perhaps a mariner’s instinct will always have a role to play, but the requirement for newer, more sophisticated, reliable and accurate methods of weather reporting at sea continues apace.

The drive for continued efficiency and change comes from an industry forced to reduce overall costs on projects and from contractors or vessel operators looking to minimize environmental impact while furthering a competitive edge, all while improving safety levels. Being able to provide comprehensive decision support covering all these needs, a trusted collaboration between the vendor and the user is a must.

Direct access to real-time sea state data 

With a sea-state-as-a-service model, it is easy to retrieve and share data to all internal and external project stakeholders simultaneously. This gives stakeholders a comprehensive overview of environmental conditions as they develop, irrespective of personnel being based onshore or offshore. Also, it provides valuable support for vessel access planning, facilitating real-time decision support during operations, providing access to historical data for post-operation analysis and leading to improved confidence in numerical spectrum forecasts and refining alpha-factor.

Alpha factor is highly important for operations where wave height and period are crucial elements to contractual fulfillment. The Miros technology is accredited by DNV, providing clients with the assurance that the data they are receiving is accurate,  and it can improve operability by expanding weather windows and minimizing time spent waiting on weather. Furthermore, allowing vessel operations to continue for longer periods of time results in cost savings and increased efficiencies during projects. Essentially, Miros aims to assist its clients in maximizing vessel operability.

Sea state data shared via a secure cloud solution in real time allows the marine sector to benefit from increased operational safety for the movement of personnel, significantly reduces costs compared to commodity wave measurement technology, and provides high data reliability and availability for notable operability improvements.

The most critical aspect is the ability to use real-time data combined with modeled or forecast data, which are being captured to improve safety and operational efficiency. Access to real-time information on sea state directly impacts decisions about conducting activities offshore or monitoring sea state during routine operations such as deployment of equipment, subsea installations, cable or pipelaying, or crew transfers.
